TO ALL WHOM 11 MAY CON GERN:

Be it known that I, WILLIAM RLCJIARDSON, of Hookstown, in the county of Baltimore, and State of Maryland, have invented a new and useful Improvement in .Vegetable-Ploughs; and I do hereby declare the following to be a full,-clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specificatiomand in which the figure is a perspective view of my invention;

In this invention, of the three plough points the forward one is removable and the two rear ones are adjustj able both laterally and vertically. The object in constructing a plough in this manner is to adapt it to ploughing between rows of different distances apart, and to adjust it cit-her to surface or subsoil ploughing, as ma-y'be desired. It also pulverizes the ground more thoroughly than the commonplough. 1 i

In order that others skilled in the art to which my invention appertaius may be enabled tomake and use the same, I will proceed to describe it in detail.

In the drawings,-A represents the drmv-beam of my improved plough, B B the side beams, C the cross I 1 beams, and D D the handles attached to the cross-beams O C. The shape of the frame is an equilateral triangle,

having the draw-beam attached at the vertex. i At the same point the forward plough E is attached to the drawbeam and frame, a pin or key confining its standard or shank in place andallowing the plough to be removed when desired. This plough has a double mould-hoard, throwing the dirt on either side. F F are boxes sliding I laterally on the rear cross-beam C, which passes through slots in the boxes: The boxes havefalso a vertical slot, through which, in front of thc,cross-beam C, pass the vertical shanks or standards of the rear ploughsGG. Set-screws H H enter the rear sides of the boxes and work against the rear side of the beam C. Bymeans he beam 0, and the plohghs are confined in their place in the boxes.

It is evident from the above dose the ploughs G- Gr may bcconfined in the bores so as either to out very deeply or verylightly in the soil, as may be desired by the operator. The rearploughs Gr G are made right and left. This position, as shown inthe drawing, may be reversed, in which case they will throw the dirt inward. When the forward plough E is in place and the rear ploughs are adjusted to throw the dirt inward, the soil will.be thoroughly pulverized, being first thrown outward and then intercepted and thrown in again by the rear ploughs. The forward plough may be removed and the two rear pioughs brou mou double mould-board plough, or either of the rear ploug in this manner be readily adjusted as a breaking-up plough, or for thoroughly pulverizing or harrowing ground that has before may he graduated, as a graduated to show exactly the depth required to be ploughed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

ripiion that the boxes may be coniined at any'point on the beam G, and

ght close together-when it is desired to use the instrument as a comhs may be removed at pleasure. The instrument may 1 plough, a side-hill plough, a corn-plough, a surface or subsoil been ploughed. The cross'beam Q t It h, to indicate precisely where to set the boxes. The plough-shanks may also be 1. The boxes F '13, substantially as and for the purpose described.

2. The graduated beam 0, for the purpose specified. 3. The graduated plough-shanks or plough-standards G G, for the purposespeciiied.

4. The arrangement of the removable plough E with the adjustable and removable ploughs G G, substant1ally as and tor-the purpose specified.

5. The combination of the plough-shanks G G, the bore substantially as and for the purpose specified.
